OHN HENRY UPTON UTTE JOHN HENRY UPION, OF DUNSMUIB, CALIFORNIA.

CAN.

Application filed September To all whom it may concern:

Be it known that I, J OHN HENRY Urron, a citizen of the United States, residing at Dunsmuir, in the county of Sislziyou and State of California, have invented certain new and useful Improvements in Cans, of which the following is a specification, reference being bad to the accompanying draw- This invention relates to certain improvements in cans and has relation more particularly to a device of this general character especially designed and adapted for use in the storage or transportation of aquatic am.- mals such as fish and it is an object of the invention to provide a device of this general character having two chambers, one or water and the other for a supply of air under pressure together with means whereby the air may be delivered to the second compartment when the requirements of practice may so necessitate.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my 1mproved can wherein certain important ad vantages are attained and the devlce rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

I In order that m invention may be the better understoodI will now proceed to de scribe the same with reference to the accompanying drawings wherein:

Figure l is a view partly 1n elevatlon and partly in section of a can constructed 1n accordance with an embodiment of my invention Fig. 2 is an enlarged fragmentary view partly in elevation and'partly in section illustrating the outer end portion of the operating stem for the valve and the co-acting mounting therefor; and

Fig. 3 is a fragmentary enlarged vertical section view taken through the upper end portion of the stand pipe and the cap or head co-acting therewith.

As disclosed in the accompanying drawlngs R denotes a receptacle or can of predetermined dimensions and configuratlon and Specification of Letters Patent.

having a substantially concavo-convex bottom 1. The can is also intersected by a concavo-convex partition 2 in predetermined spaced relation relative to the bottom 1 and the space between the bottom 1 and partition 2 affords an air chamber to hold air under pressure. Extending within the air chamber through a side wall of the receptacle R is a tube 3 substantially wholly confined within the air chamber and open at opposite ends. Arranged within the inner end portion of the tube 3 is an inflating valve 4:

of any ordinary or preferred construction and with which is adapted to be coupled any suitable form of air compressor such as a tire pump or the like. Extending upwardly from the partition 2 at substantially its axial center is a stand pipe 5 in communicat1on with the air chamber and having interposed therein a valve 6 of any ordinary or preferred type and which valve is adapted to be operated by the laterally directed stem 7 In threaded engagement with the upper en portion of the stand pipe 5 is a cap or hea substantially spherical in form and provided with a recess 9 in communication with the stand pipe 5 when the cap or head is in applied position. The cap or head is provided with a series of radially disposed restricted openings 10 extending therethrough and in communication with the recess 9 and disposed on a predetermined downward incline. In practice it has been found best to have the openings 10 disposed on an angle of substantially 30 relative to the horizontal and to have each of said openings of a diameter of one-sixteenth of an inch.

When the valve 6 is in an open position the air within the chamber below the parti tion 2 will escape into the upper chamber and pass through the water within such upper chamber in minute bubbles and which provision in a device of this character is of manifest advantage.

The side wall of the receptacle or can It is provided with an inwardly directed sleeve 11 having one end opening into the atmosphere while the opposite end 12 is closed. Said closed end is provided with the restricted opening 14; through which the outer end portion of the stem 7 is snugly directed. The stem 7 is of such a length as to have its outer or free end terminate inwardly of the open end of the sleeve as is particularly illustrated in the accompanying drawings. The central portion of the inner wall of the sleeve 11 is internally threaded as at 15 and with said threaded portion is engaged the packing nut 16 through which the free end is also directed. The opposed faces of the packing nut 16 and the closed end 12 of the sleeve 11 are concaved and interposed between said closed end 12 and the nut 16 is suitable packing 17. By this arrangement it will be at once self evident that the escape of Water Within the upper chamber through the sleeve 11 is pre-- vented. It is to be understood that fish or other aquatic animals are placed within Water carried Within the chamber above the partition 2.

From the foregoing description, it is thought to be obvious that a canconstructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it ma e assembled and operated and it will also be obvious that my invention is susceptible of some change and modification without portion of the stem 7 precise arrangement and formation of t e several parts herein shown 1n carrying out my invention in practice except as hereinafter claimed.

I claim:

In combination with a can, a partition dividing said can into two compartments, one of said compartments being adapted to contain water and the second compartment being adapted to contain air under pressure, a stand pipe carried by the central portion of the partition and in communication with both of the compartments, said stand pipe extending within the compartment adapted to contain water, a valve interposed in the stand pipe, an inwardly directed sleeve carried by a side wall of the can and extending within the compartment adapted to contain Water, the outer end of said sleeve opening to the atmosphere, the opposite end of the sleeve being closed, and an operating stem for the valve within the stand pipe: extending within the sleeve through the closed end JOHN HENRY UPTON.
